Methods and apparatuses for communication between lightweight machine to machine (LwM2M) client and server are disclosed. According to an embodiment, a network exposure node performs configuration such that the network exposure node can transfer traffic between a LwM2M client and at least one LwM2M server over non-Internet protocol data delivery (NIDD) through reliable data service (RDS) protocol. The network exposure node transfers traffic between the LwM2M client and the at least one LwM2M server based on the configuration.
